Highland Railway Dia 17 Jones Double Deck Sheep Wagon

Initially the Highland Railway used modified open wagons to carry sheep - they had greedy bars fitted to stop the sheep jumping out, and a hole in the sides to let any fluids drain out.

To allow the transportation of more sheep, and to better protect the sheep they produced double decked wagons. The Jones version had double sliding doors per level, and may have had the decks split to allow 4 seperate shipments per wagon. The ends being vented planks, the side being verticle bars.

So the last few days have been spent drawing this up

Progress so far





Now not sure if some of the detail will print - like the chains on the pins holding the doors closed



Still got the brackets to complete on the outside and the internal brackets for the floors before duplicating to produce the other side.

The intention is to print it with seperate floors as per the other vans I've made and set parallel to the build plate. I think plenty of internal bracing will be needed to protect the bars.

Then I discovered that the doors stood out too far, and the slide rails were beyond the roof - evidently the 2D drawing doesn't occupy 3D space. Adjustments made, but leading to a rebuild of the locks



And each link has to be in physical contact with the next to be able to join them together - we'll see if the effort was worth it at print time. The shed was at a cosy 4C on Friday, Saturday I'd be better off with a boat. And now the sun's shining, away to the club to see if it survived all the flooding. Should be fun as we've had a frost overnight, so with all that water I may be taking the car for a spot of ice skating

Gary it does look very similar - although your sheep must have weaker bladders with the need of an internal roof for drainage.

Four sides now completed



And sole bars nearly done



Rear solebar needs an extra plate adding as the front righthand one is ommited due to the Brake J hanger covers it.

Hopefully the W irons, Brake assembly & springs are the same as the Jones built Timber wagons.

Paul

 

Fair point

Well there's good and bad news on the recycling front



The springs from the D4 Type Q van fit , but the W irons dont, and the brake assembly is close, but ........ oh well
I knew the axleboxes and buffers were different, back to the drawing board as they say ....

Paul

 

W iron knocked up



However I think its time for bed before I start on the axlebox and brake gear

Paul

 

Another late session





Just the floors and brake J hanger, oh and the buffers as the're different as well

On the Vans, I printed the body parallel to the build plate, with the floor printed seperately. I wish to do the same with this, but have the issue with two floors and not a lot of solid space in the sides.

My idea is to support the upper floor with braces as per the drawing and printing these as part of the main body, again printing the upper floor as a separate item inserted during construction. This would prevent me from inserting the lower floor from the top as per the other vans.

Cross braces added including the retaining brackets.



Then added the floor



and from above



A bit more playing required to get the lower floor so it fits and allows the model to be assembled.

Starting to look the part



Just need to sort out the lower floor but is getting close.

I'm with Mossy on this one, after seeing your building work, these vans would be a doddle for you.

I do find the drawings aren't always correct between elevations, so need a bit of tweaking to correct / fudge.

Essentially they are just a collection of bits, so far 76 sketches have produced over 300 bodies, which have made currently 17 seperate parts, which will reduce further until the wagon is completed which will be somewhere around 10 parts.

I've yet to try paneled sides with a tumblehome, Mossy has sent me a couple of tips on how to do the tumblehome and panels, so may try a horsebox then maybe some 6 wheel coaches.

I haven't tried a loco in Fusion yet, but have a couple of potential targets up my sleeve.

Paul

 

Hi Mossy - looking forward to tumblehome and panelling tutorial.

The lower floor has been split in half to allow them to be inserted from the underside - a test print will be needed to see if this will work.

I have added blocks on the solebars for alignment of the W irons, and added a base to the W iron to give strength and a greater gluing surface.



Test layout in Chitubox using the Mono X



Estimated print time of 3 hours 20 mins - we shall see.
The floors are being printed at 85 degrees.
I need to redo the body model as this was created before I did the mods to the solebars for the W iron alignment.

Paul

 

And the buffers,



I think this is almost there ....... I know I should leave the thinking to others

Paul

 

And overlaid over the drawing

Finally got the first test print started - unfortunately it was printed on Mono Number 2 so is using Anycubic ABS+ resin, so its harder to see the fine detail.

The bars are 0.6 mm and are distorting and in a couple of places have broken.

Gives me two options, try increasing the size to 0.8 mm or remove the bars and have holes to thread 0.6 mm brass wire in.

Oh boy do I love the time line in Fusion 360.

Firstly found the sketch used to create the bars - note to self name the sketches, as this sketch was named sketch 30.

By finding the sketch location in the time line, and moving the time line cursor to that point. I then edited the sketch, and for each value changed it from 0.6 to 0.8 - all 26 of them.
Once saved the time line cursor was moved to the end, a few worrying moments later a couple of re-calculating messages were displayed and finally resized bars showed up all round.

Another test print

And every bar printed - there are some dangly bits - they are the rails for the sliding doors - need to apply more fine supports - just tweaking.

The floors and roof fitted

left to right Roof, Upper floor and two lower floors.

Lower floor inserted from below (hence the two parts, I may try printing it as a single item.

Upper floor fitted

And the roof

The other parts to complete the model have been printed ready to try a test build

Need to take pics - I'll be back

 

Buffers

Brake assembly, Brake pivot and Brake lever

W irons and Axlebox

The leaf springs are the same as the Jones 8 Ton vans
